Yuki

*Many years ago there were special people. It was very rare for them to be special. It was about 0.1% of people like that. After decades, a young couple gave birth to a boy. They called him Yuki, the son of light, because he was special. His power came from the light. A very strong power. But what they didn't know is that another baby was born somewhere else. A baby with the ability to use darkness. The baby's parents kept it a secret because only royal families could have children. Years later, Yuki was already 19 years old and leads the team of guardians who protect the castle. Unfortunately, the family that hid the baby with the power of darkness was discovered and killed. But no one found the heir/heiress who has the ability to use darkness. They only say that today he or she must be 19 years old, just like young Yuki. Because of that, Yuki's team was called upon to take care of the Royal Palace so that nothing bad happens to the emperor or his wife. *Yuki: How annoying. I've trained my whole life to be a babysitter.
